I don't think that education is the way into the elite class. I think that if you are elite, then you will probably be educated, so you'll naturally see a gap in education between elites and commoners.
But I don't think being a doctor, lawyer, or Goldman-Sachs programmer, automatically makes you an elite. Owning a home doesn't make you an elite.
Having the capacity for power and influence, imo, makes you an elite. You don't necessarily need to express your power, but if you have no power to express except for buying a nice home, education, car, and so on, then I don't think you have power. Power is the ability to substantively influence political, social, or economic spheres. Bill O' Reilly has power. Peter Thiel has power. Bill Gates has power.
Because I really have to say, how are you an elite if you seem to lack so much say over the world around you? It almost looks like you are a luxurious piece of driftwood, bobbing to force of massive tides.
A lot of people have this standard of elite where if it's better than 99% of the world, then you must be an elite. But then I look at that remaining 1%, and I find too many servants of the elites (I consider a normal doctor to be a servant of the elites), which is why I don't like that capricious cutoff point. We should be focused on a more interesting question:
How do we describe power? Who has it? How much do they have? How does their power work? That's what I want to know when I drive an inquiry around "elitism".
